MySQL查询导致Magento Store出现高CPU峰值

Question

由于以下MySQL查询一直在运行，我的Magento商店的CPU使用量突然大幅增加：

SELECT 
    `d`.`entity_id` 
FROM 
    `catalog_category_entity_int` AS `d`
LEFT JOIN 
    `catalog_category_entity_int` AS `c` ON c.attribute_id = '42' AND     
    c.store_id = '1' AND 
    c.entity_id = d.entity_id 
WHERE 
    (d.attribute_id = '42') AND 
    (d.store_id = '0') AND 
    (d.entity_id IN 
    (SELECT 
        `e`.`entity_id` 
    FROM 
        `catalog_category_entity` AS `e` 
    WHERE 
        (`e`.`entity_type_id` = '3') AND 
        (`e`.`entity_id` IN
        ('4', '31', '71', '72', '450',
        // this continues to contain around 2000+ id's...

我不知道这是从哪里来的或是什么导致了这个？任何人都可以帮助解释这是在尝试什么，以及是否有任何建议是什么导致它？
